Just to add a bit to this I have two Ruger P95s, a Ruger GP-100, SP-101, P97DC, two Ruger rifles,and a SR-9 and the SR-9c model.
One did go back for a problem. The SR-9. It was one of the first batch out and had safety issues. It was returned, fixed, and utterly reliable now.
CS worked with me through the whole thing with no problems. Was I happy. Heck no, but I realized that working through the problem in mature manner was better all around then going off on a fit.
It can be expected that when a new gun goes wonky ( that's a scientific expression.... NOT) that the owner will be very miserable and may want to vent. That happens. No problem. But then the problem needs to be worked through to a satisfactory conclusion as much as possible. And that is in a manner described above. Mature and well thought out.
We've all been here or at other gun forums when brand X or Y gets trashed. You can't broad brush a company because of one or several bad experiences. Verifable overwhelming amounts of hard core data is needed for that. Lots of it.
Inspecting the gun closely before purchasing is important. That cuts down on a lot of gripes and dis-satisfaction.
I like Ruger products. Are the end all? No. But as already noted some do get out of the factory and are unsatisfactory. It happens for the other brands as well. Will I defend Ruger to the death? No. They've had their faults like everyone else. Let it go and get on with life.
One can either decide to work things through with CS, and send the letter, sell, the gun as is and let the new owner know what they are in for, or keep the gun, but that would not be in the best interests of the OP.
I could have gone to the 2 Ruger forums and wailed, gnashed my teeth,and complained how I was wronged. That was not done. No reason for it.
